It's FAST.
Sharpness, color balance e contrast.
Bokeh.
Cons:
Vignetting at f1.4
It cannot zoom :)
I sold my 24-70 2.8 after I got this. It's an other world from 1.4 to 5.6.
Color balance it's impressive, more neutral, the zoom has a yellow cast in comparision.
Super fast focusing.
Perfect lens for indoor available light family pictures.
